ISR Performance GT Dual Exhaust - 98-05 Lexus GS300

The ISR Performance GT Dual Exhaust for the 1998-2005 Lexus GS300 is a complete catback that splits a 3" mid pipe into dual 2.5" rear sections with 4.5" polished tips. Mandrel-bent stainless construction, brushed finish, polished mufflers. the right setup for a 2JZ-GE that deserves more than the factory exhaust gives it.

What It Does

Catback replacement for the GS300. The 3" mid pipe handles the bulk of the flow, splits into dual 2.5" pipes through the rear muffler section, and exits through twin 4.5" polished tips. Works equally well on naturally aspirated 2JZ-GE setups and the 2JZ-GTE swaps that GS300s sometimes end up wearing. TIG-welded throughout, brushed stainless finish on the piping, and polished mufflers and tips for the visual upgrade.
